AWS Well-Architected Framework
The AWS Well-Architected Framework provides best practices across six pillars:
1. Operational Excellence
- Automate infrastructure provisioning and configuration
- Monitor and measure system performance
- Continuously improve processes and procedures
2. Security
- Implement strong identity foundation
- Enable traceability and audit logging
- Apply security at all layers
- Protect data in transit and at rest
3. Reliability
- Automatically recover from failure
- Test recovery procedures
- Scale horizontally for resilience
- Manage change through automation
4. Performance Efficiency
- Use appropriate resource types and sizes
- Monitor performance and adapt
- Leverage serverless architectures
- Experiment with new technologies
5. Cost Optimization
- Adopt consumption-based pricing
- Measure and monitor spending
- Use cost-effective resources
- Optimize over time
6. Sustainability
- Understand environmental impact
- Maximize utilization of resources
- Use managed services
- Reduce downstream impact
Compute Services

1. Security: Always encrypt data at rest and in transit, use least privilege IAM policies, enable MFA 2. High Availability: Deploy across multiple Availability Zones, use Auto Scaling 3. Cost Optimization: Right-size resources, use Reserved Instances/Savings Plans, implement lifecycle policies 4. Performance: Use caching (CloudFront, ElastiCache), optimize database queries, leverage CDN 5. Reliability: Implement automated backups, test disaster recovery procedures, monitor everything 6. Operational Excellence: Automate deployment with Infrastructure as Code, implement CI/CD pipelines 7. Sustainability: Use managed services, optimize resource utilization, shutdown non-production resources

Architecture Best Practices
Security
1. Use VPC: Always deploy resources in a VPC 2. Security Groups: Implement least-privilege access 3. Encryption: Enable encryption at rest and in transit 4. IAM: Use roles instead of access keys 5. CloudTrail: Enable for audit logging 6. Secrets Manager: Store credentials securely
# Create a secret in Secrets Manager
aws secretsmanager create-secret \
--name prod/db/password \
--secret-string "MySecurePassword123"High Availability
1. Multi-AZ: Deploy across multiple Availability Zones 2. Auto Scaling: Automatically adjust capacity 3. Load Balancing: Distribute traffic evenly 4. Health Checks: Monitor application health 5. Backups: Automated and tested regularly
Cost Optimization
1. Right-Sizing: Use appropriate instance types 2. Reserved Instances: Commit for 1-3 years to save up to 75% 3. Spot Instances: Use for fault-tolerant workloads (up to 90% savings) 4. Auto Scaling: Scale down during off-peak hours 5. S3 Lifecycle: Move data to cheaper storage classes 6. CloudWatch: Monitor and optimize resource usage
# Set up S3 lifecycle policy
aws s3api put-bucket-lifecycle-configuration \
--bucket my-bucket \
--lifecycle-configuration file://lifecycle.jsonPerformance
1. CDN: Use CloudFront for static content 2. Caching: Implement ElastiCache for databases 3. Database Optimization: Use read replicas, connection pooling 4. Async Processing: Use SQS/SNS for decoupling 5. Serverless: Use Lambda for event-driven workloads
